SPECIFICATION forming part of Letters Patent No. 336.526, dated February 16. 1886.

Application filed August 10, 1885. Serial No. 174,045. (No model.)

T @ZZ whom it may concern.-

Be it known that I, TILLMAN PUErz, Jr., of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Plug-Tobacco Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of t-his specication, and in whichb ignite l is afront end View of niy improved machine, the cog-wheel and pinion being omit# ted. Fig. 2 is a rear view of the same. Fig. 3 is an end view of the cam-drum removed. Fig. 4 is a top View showing a charger in its forward position. Fig. 5 is a similar view showing the charger back. Fig. 6 is a horizontal section taken on line 6 6, Fig. l. Fig. 7 is a similar view taken on line 7 7, Fig. l. Fig. is aside elevation showing the charger in its forward position. Fig. 9 is a similar View showing the charger back. Figs. 10 and ll are detail vertical sections taken on line l0 l1, Fig. 4, Fig. 10 showing the parts in the position they occupy when the plug is formed, but before it is ejected from the machine, and Fig. l1 showing the parts in the position they occupy when the plug is ejected.

My invention relates lto certain improvef ments in plug-tobacco machines, for which Letters Patent Nos. 330,849 and 330,850, were granted on the 17th of November, 1885; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the frame of the machine,supporting a main shaft, B, in journal-boxes B'. On the outer end of this shaft is a cog-wheel, B2, engaged by a pinion, B3, on a shaft, Bt, journaled in brackets or boxes B5, secured to the frame of the machine. This latter shaft is provided with a driving-pulley, B6, through which motion is imparted to the machine.

On the shaft B is a drum, O, carrying a number of cams on its outer periphery.

The charger D consists of side pieces, D', front piece, D2, and back piece, D. The front piece has tongue-and-groove connection with and is carried by the side pieces, but the back piece is not attached to the side pieces, but moves independently thereof.

' D4 are guides for the charger on the table A'.

ing the roller the front and back pieces of the charger, as

shown in Figs. 10 and 1l, and forms a bottom to the charger and a discharging device.

Secured to the outer ends of the rods E by means of the nuts E' is a cross-head, G, having a sliding support, G', dovetailed into the table of the machine, as shown invFig. 2, and provided with friction-rollers Gthat bear upon the table as the charger is worked back and forth. Passing down through this cross-head is a bolt, H, on the lower end of which is a frietionroller, H', engaged by a cam, I, on the periphery of the drum O, to force the charger forward, and engaged by a cam, I', also on the periphery of the drum,to cause the charger to be moved back.

Fig. 9 shows the cam I. about to engage the roller to force the charger forward.

Fig. 10 shows the cam as it is about to leave the roller, and at this point it has a portion, I3, that is transverse of the drum, the office of which is to hold the charger a short time in its forward position before the cam leaves the rollei.

Figs. 8 and 11 show the cam I' before reachto cause the chargerto be carried back. rlhere is a space, I2, between the releasing end of the cam I' and the engaging end of cam I, as shown in Figs. 8 and l1, for the passage of the roller from the former to the latter. As the cam commences the forward movement of the charger, as described, the rear part, D, of the charger is rst carried forward until the tobacco is 4sufficiently pressed to move the charger forward bodily, as shown and described in said Letters Patent, and when the charger has reached the position shown in Figs. 8, 10, and 1l the plunger I' 1s brought down against the tobacco on a stationary bed or plate, J, as shown in Fig. 10. This plunger is raised and lowered by the following means: Lrepresents a sliding block dovetailed into a standard orbed-plate, L', and connected by means of links L2 to toggle-bars L. The upper toggle-bars L3 are pivoted at their up per ends to the frame of the machine, as shown at L, and are `connected at their lower ends IOO to the lower tog 3;le-bars by a pin, L6. The lower toggle-bars are connected at their lower ends to a vertical sliding rod or beam, Ll, working in slots L8 of the frame of the Inachine, and they preferably have slots L1", through which the rod or shaft passes, these slots allowing for lost motion, in case lost motion is required. The rod or beam L7 is connected to the plunger by means of two vertical rods, L,passing through guides L,securcd to the table of the machine; and it will be seen that as the toggle-bars are forced forward the plungerwill be pulled down to press the tobacco, and as the toggle-bars are pulled rear` ward back again from the position shown in Fig. 8 to that shown in Fig. 9 the plunger will be elevated again.

M represents the cam on the drum for forcing the plunger down.

Fig. l0 shows the cam M engaging with the projection L13 on the sliding bloclgand shows the parts in the position they occupy just as the block has been forced back to the limit of its movement to lower the plunger. From this point the cam extends around the periphery in a line transverse of the drum, and when the drum is turning the plunger is thus held in its position, giving time for the tobacco to be thoroughly pressed. This cam ceases at M', Figs. 8, 9, 10, and ll, and then acam, N, comes against the projection on the sliding block and forces the block and toggle-bars from the position shown in Fig. Sto that shown in Fig. 9, and this latter cam has a portion, N, transverse of the drum, which holds the plunger in its elevated position until the proper time comes for it to be again depressed, then the projection will pass through a space, O, at the end of this cam and the end of the compressing-cam M. Just as the plunger starts to rise,the front end of the charger is elevated by the following means:

K represents a lever pivoted at K to the frame of the machine, and connected by its outer end to a rod, K2, made fast to the lower end of a yoke-frame, K3, passing through guides K4, secured to theframe of the machine, and engaged by lugs K5 on the front part of the charger (see Fig. ll) when the charger is in its forward position. This front part of the 'charger has vertical movement from the position shown in Fig. 10 to that shown in Fig. 11, by means of its tongueand-groove connection with the sides of the charger. The inner end of the lever K fits in a cam-groove, O, in the front part of the drum C, (seeFigs. l, 3, 10, and 11,) the groove being annular until it reaches an offset, O5, and as the inner end of the lever enters this offset its outer end is elevated, causing this upward movement of the front part of the charger, thus permitting the plug to beremoved from beneath the plunger, which has, as stated, just started to rise. As soon as the plug has been ejected, the front part of the charger is pulled down again by the end of the lever emerging from this offset Q5 in the annular cam-groove. The plug is ejected by the sliding plate F, which is forced forward and backward by means of cams l?, between which fits a friction-roller, F1", depending from the plate. Vhile the plate is in its normal position, the roller fits between the parallel parts of the cam, and when it is to be forced forward the roller passes between the V-shaped projection P2 of the cam. (See Figs. 6, 8, and 1l.) The V-shaped projections of the cam are made quite acute, so that the movement ofthe plate is rapid, being forced forward j ust at the timethe front of the charger is elevated, as shown in Fig. 1l, and then Vbeing pulled back immediately before the front part of the charger is again lowered to its normal position. Vhen the plate is pulled back and the front part of the charger pulled down to its normal position, the charger is moved' back to receive another quantity of tobacco, when the operation above described is repeated.

It will be seen that the charger, the plun ger, the sliding plate for ejecting the plugs,and the movable front end of the charger are all operated from a single earn-drum, and as this drum can be cast in one piece at one operation it can be quickly and cheaply produced, and the form of the drum permits the compressing cam M to have a long surface thatwill hold the plunger in its lower position, to give time for the tobacco to be v rendered compact before the pressure is removed. The cams I and I are made higher than cams M and N, so that the roller H will not have to be placed so low as to strike these latter cams, yet it is low enough to strike its own cams I and I.

To assist the toggle-bars L8 in lifting the plunger, if required, I pivot two levers, I, to the frame of the machine, connected at one end to the sliding block L by two links, T, and at the other end they extend beneath the rod or beam L7. As the block is moved from the position shown in Fig. 8 to that shown in Fig. 9, the free ends of the levers press against the rod Ll, as shown.
